Nobel Peace Prize winners like Wangari Maathai don't seem to think it's 'crazy talk' (which characterization is very offensive, btw - where is the moderator now?)
So no, it's actually not 'crazy' at all, but from the perspective of a government that has tested radiation on people without their knowledge or consent, has tested syphilis on people, and that has conducted all kinds of human tests (e.g., http://en.wikipedia.org/wiki/Project_MKULTRA) it's very well within the realm of possibility.
And did you forget? It's also unsubstantiated that XMRV is a cause of ME/CFS. So intentionally or otherwise, your comments there are a bit ironic aside from being offensive.
Barack Obama won the Nobel Peace Price for doing nothing- using the significance of an individual who shares your view is one of the basic logical fallacies you will learn in philosophy 101.
As per the syphllis, etc. - it might be a good idea to use examples that are not 70 years old. And among those examples you might want to find ones where the Government actually engineered a virus, and disseminated it.
As it turns out, creating a retrovirus isn't quite the simple scientific project you seem to think it is.
The problem with conspiracy talk is that any idiot can sound knowledgeable by simply alleging things they can't possibly prove- just like the 911 conspiracy theorists. And then the burden of their wild speculations falls on everyone else.
Children do that with no sense of the gravity of their words. Grown ups should know better.
Is that insulting? Yeah, probably. But accurate.
